The performance standard AHRI/ASHRAE/ISO 13256-2 became effective January 1, 2000. This new standard has three ma-

jor categories: Water Loop, Ground Water, and Ground Loop.

Unit of Measure: The Cooling COPThe cooling efficiency is measured in EER (US version measured in Btuh per Watt. The Metric version is measured in a

cooling COP (Watt per Watt) similar to the traditional COP measurement.

Pump Power Correction CalculationWithin each model, only one water flow rate is specified for all three groups and pumping Watts are calculated using

the following formula. This additional power is added onto the existing power consumption.

• Pump power correction = (gpm x 0.0631) x (Press Drop x 2990) / 300

Where ‘gpm’ is waterflow in gpm and ‘Press Drop’ is the pressure drop through the unit heat exchanger at rated water

flow in feet of head.

ISO Capacity and Efficiency CalculationsThe following equations illustrate cooling calculations:

• ISO Cooling Capacity = Cooling Capacity (Btuh) x 3.412

• ISO EER Efficiency (W/W) = ISO Cooling Capacity (Btuh) x 3.412 / [Power Input (Watts) + Pump Power Correction (Watt)]

The following equations illustrate heating calculations:

• ISO Heating Capacity = Heating Capacity (Btuh) x 3.412

• ISO COP Efficiency (W/W) = ISO Heating Capacity (Btuh) x 3.412 / [Power Input (Watts) + Pump Power Correction (Watt)]

Control and Safety Feature Details

Emergency Shutdown

The emergency shutdown mode can be activated by acommand from a facility management system or a closed contact on BI-2. The default state for the emergency shutdown data point is off. When the emergency shutdownmode is activated, all outputs will be turned off immediatelyand will remain off until the emergency shutdown mode is de-activated. The fi rst time the compressor starts after theemergency shutdown mode has been de-activated, there will be a random start delay present.

Lockout ModeLockout mode can be activated by any of the following fault signals: refrigerant system high pressure, refrigerantsystem low pressure, heating freeze detection, coolingfreeze detection, and compressor current sensor. When any valid fault signal remains continuously active for the length of its recognition delay, the controller will go into faultretry mode, which will turn off both compressors. After the compressor short cycle delay, the compressors will attempt to operate once again. If three consecutive faults occur in 60minutes, the unit will go into lockout mode, turning off the compressor(s), enabling the alarm output until the controller is reset. If the control faults due to the low pressure input being open during the pre-compressor startup check, the control will go into lockout mode immediately, disabling the compressors from starting and enabling the alarm output. The lockout condition can be reset by powering down thecontroller, by a command from the BAS, or by the holdingthe ESC and Return keys on the user interface for 5 seconds. NOTE: See freeze detection section for more detail.

Controls - FX10 cont.

Reversible Chiller Advanced FreezeDetection SystemThe reversible chiller source and load heat exchangers are

protected by a multi-sourced temperature logic strategy. The

temperature logic is based upon the refrigerant temperature

sensed as the refrigerant is about to enter the heat

exchanger; while entering and leaving water temperatures

are being used as correlating factors. The detection scheme

is shown as basic and advanced algorithms.

Basic Freeze Detection Operation: “Comp1 orComp2 Freeze” Alarm

This alarm can be triggered by one of two detection schemes.

Hard Limit Freeze DetectionIf the refrigerant temperature drops below the freeze

detection setpoint by 1.8°F, the associated compressor

is locked out immediately regardless of any other

factors and requires a manual reset. NOTE: This Lockoutproduces a “Comp 1 or Comp 2 Freeze” error on the MUI display.

Freeze DetectionThe refrigerant temperature is compared to the freeze

detection setpoint (15°F [antifreeze] or 33°F [water]

field selectable), and if the temperature falls below the

setpoint for 30 continuous seconds, the associated

compressor will be halted. This function becomes

enabled after the first two minutes of compressor

operation. Three such events in 60 minutes will trigger a

compressor lockout that requires a manual reset. NOTE:This Lockout produces a “Comp 1 or Comp 2 Freeze” error on the MUI display.

In addition to the above:Entering Water Temperature InfluenceIf the entering water temperature of the evaporative

heat exchanger is within 10°F of the freeze setpoint,

the previously mentioned two minute delay will be

eliminated. This allows the freeze detection to operate

immediately when the compressor starts based on

entering water temperature.

Leaving Water Temperature InfluenceIf the leaving water temperature of the evaporative

heat exchanger is within 10°F of the freeze setpoint, the

previously mentioned 30 second delay will begin to be

proportionately reduced, ending at a 1 second delay

when the leaving water temperature is 1.5°F above the

freeze setpoint.

Dual Circuited Heat Exchanger ProtectionA low temperature condition on either refrigerant circuit

will prevent the start of both compressors. If the low

temperature condition exists for 5 minutes when both

compressors are off, a lockout is triggered for both

compressors. However, if for instance both compressors

are operating and circuit 1 experiences a refrigerant

temperature below the freeze detection setpoint such

that compressor 1 is halted, compressor 2 will not be

halted as a result.

Advanced Freeze Detection Operation: “PreFreeze” Alarm

Predictive freeze condition detection:If the refrigerant temperature is within 7.2°F of the

freeze detection setpoint, the predictive freeze

detection algorithm is enabled, and if the logic

determines that a freeze condition is likely to happen

based on current conditions, the compressor of the

involved refrigerant circuit is immediately stopped.

Three (3) such events in 60 minutes will trigger a

compressor lockout that requires a manual reset. In the

absence of such a condition, the compressor is allowed

to operate so that the refrigerant temperature may

eventually be at the threshold of the freeze detection

setpoint. NOTE: This Lockout produces a “Pre Freeze” detection error on the MUI display.

Capacity Limiting

If the leaving water temperature drops to 1.8°F above the

freeze detection setpoint, the lead compressor is halted.

When the leaving water temperature rises to 3.6°F above

the freeze detection setpoint, it will be allowed to resume

operation. This limiting is allowed to repeat indefinitely with

no lockout or indication on the display.

If the leaving water temperature drops to the freeze

detection setpoint, the lag compressor is halted. When the

leaving water temperature rises to 1.8°F above the freeze

detection setpoint, it will be allowed to resume operation.

This limiting is allowed to repeat indefinitely with no lockout

or indication on the display.

High Pressure

The high-pressure switch shall be a normally closed (NC)

switch that monitors the systems refrigerant pressure. If the

input senses the high-pressure switch is open it must disable

the compressor output immediately and count the fault. The

compressor minimum on time does not apply if the high-

pressure switch opens. The compressor will not restart until

the compressor short cycle time delay has been satisfied.

14


Controls - FX10 cont.Low Pressure

The low-pressure switch shall be a normally closed (NC)

switch that monitors the systems refrigerant pressure. The

input 15 seconds before compressor start up and then

ignored for the first 2 minutes after the compressor output

(BO-2) is enabled. If the switch is open continuously for

30 seconds during compressor operation the compressor

output (BO-2) will be disabled. The compressor will not

restart until the compressor short cycle time delay has

been satisfied.

Alarm Outputs

The control has two alarm outputs, one for each compressor

circuit. These 24VAC outputs are designated as LC1

(compressor 1) and LC2 (compressor2) on the low voltage

terminal board.

Test Mode

By holding the ESC and down arrow keys on the MUI for 5

seconds will put the control into test mode. In test mode

the random start delay and the compressor fixed on delay

time will both be shortened to 5 seconds and the reversing

valve will be allowed to cycle with out shutting down the

compressor. If an MUI is connected to the control LED 8 will

flash and the words “Test Mode Enabled” will be shown on

the LCD display when the control is in test mode. Test mode

will be disabled after a power cycle, 30 minute timeout, or

by holding the ESC and Up arrow keys on the MUI.

Sequence of OperationPower Fail Restart

When the controller is first powered up, the outputs will be

disabled for a random start delay. The delay is provided to

prevent simultaneous starting of multiple heat pumps. Once

the timer expires, the controller will operate normally.

Random Start Delay

This delay will be used after every power failure, as well as

the first time the compressor is started after the control exits

the unoccupied mode or the emergency shutdown mode.

The delay should not be less than 1 second and not longer

than 120 seconds. If the control is in test mode the random

start delay will be shortened to 5 seconds.

Lead Compressor Start Delay Time

The Lead Compressor Fixed On Delay Time will ensure that

the lead compressor output is not enabled for 90 seconds

after the control receives a call to start the compressor. This

delay is adjustable from 30 – 300 seconds over a BAS or a

MUI. If the control is in test mode the Lead Compressor Start

Delay Timer will be shortened to 5 seconds.

Lag Compressor Start Delay Time

The Lag Compressor Fixed On Delay Time will ensure that

the lag compressor output is not enabled for 90 seconds

after the control receives a call to start the compressor. This

delay is adjustable from 30 – 300 seconds over a BAS or a

MUI. If the control is in test mode the Lag Compressor Start

Delay Timer will be shortened to 5 seconds.

Compressor Minimum On Delay

The compressor minimum on delay will ensure that the

compressor output is enabled for a minimum of five (5)

minutes each time the compressor output is enabled. This will

apply in every instance except in the event the high pressure

switch is tripped, freeze protection, or emergency shutdown

then the compressor output will be disable immediately.

Compressor Minimum Off Delay Time

The compressor minimum off time delay will ensure that

the compressor output will not be enabled for a minimum

of five (5) minutes after it is disabled. This allows for

the system refrigerant pressures to equalize after the

compressor is disabled.

Compressor Lead/Lag

Compressor lead/lag is a standard part of the FX10 control

system. The unit is shipped from the factory with lead/

lag enabled. Lead/lag can be activated through the unit

mounted user interface.

Heating Cycle

The control will run the unit in heating mode when there is a

command on the O/B terminal on the terminal board.

Cooling Cycle

The control will run the unit in cooling mode when there is

no command on the O/B terminal on the terminal board.

MUI Alarm History Reporting

If a fault occurs the fault will be recorded in history for

display on the medium user interface in the History Menu.

Each fault type will be displayed in the history menu with

a number between 0 and 3. A reading of 3+ will mean that

fault has occurred more than three times in the past. The

history menu can be cleared with a power cycle only. Alarm

date and time are not included in the history.

Inputs and Outputs ConfigurationField Selectable Options

Load and Source Freeze Detection SetpointThe freeze detection setpoint input allows you to adjust

the freeze detection setpoint for either the load or source

sides of the heat pump. When the jumper is installed

on BI-5 the load freeze detection setpoint is factory set

for 30°F. When the jumper on BI-5 is removed the load

freeze detection setpoint will be 15°F. When the jumper

is installed on BI-4 the source freeze detection setpoint is

factory set for 33°F. When the jumper on BI-4 is removed

the source freeze detection setpoint will be 15°F. NOTE:Piping circuit must be antifreeze protected to the set levels or the warranty will be voided.

Accessory OutputThe Accessory Output will be energized 90 seconds prior

to the lead compressor output being energized. When

both compressor outputs are turned off the accessory

output will be deactivated immediately. This output is

selectable for normally open or normally closed operation

through the Medium User Interface or through the

Building Automation System.

Controls - FX10 cont.

Reversible Chiller Setpoint ControlThis control software is by default set to operate in‘Aquastat’ mode, which requires external setpoint logic togenerate the Y1 or Y2 call. The mode may be changed to‘Setpoint’ by use of the ‘Settings’ menu in the MUI in the ‘Mode’ item which is on the 5th line from the top.

CAUTION! Setpoint mode is not recommended on applications that have more than two water-to-water heat pumps installed. Uniquetemperature setting should be set for each uniton a common load.

To operate in setpoint mode, consider the following:

• The selected mode must be changed from Aquastatto Setpoint

• The ‘Y1’ input must be activated. This may be done by connecting ‘R’ to ‘Y1’ on the terminal board, or bycommanding Y1 to ‘ON’ in the Maint menu of the MUI, or by commanding the ComprEnable network variable from the BAS.

• The Heat/Cool mode is by default in the cooling mode,and may be set to heating by connecting R to O/B onthe terminal board, or by commanding the ‘B’ itemin the Maint menu of the MUI, or by commanding the reversing valve variable from the BAS network.

• The setpoint mode temperature sensor can be selectedto either Load LW Temp (Leaving Water) or Load EW Temp (Entering Water Temp). The default is set forEntering Water Temp control.

• The cooling setpoint and the heating setpoint are two separate setpoints, and can be adjusted in the MUISettings menu.

• When the controlling temperature sensor is set toselect the Load EW Temp, the setpoint control will operate in a PID (Proportional-Integrating-Derivative)mode. In this mode, the temperature rate of changeand direction of change will be part of deciding whether or not to add or reduce capacity. Additionally the amount of difference between setpoint andtemperature AND the length of time that the difference existed are used to determine if adding or reducingcapacity is needed.

o The tuning parameters for this mode should only be adjusted if you know why you are choosing the value that you plan to use. You should keep a permanent record of the beginning valuesand record any changes that you make. The parameters used in PID operation and their (default values) are:

• D NegThrshld (-0.03)• Int Rate (200)• Stage Delay (30)• Gain (2)• D PosThrshld (0.04)• PIDY1 Ref (7.2)• PID Y1 Diff (7)• PID Y2RefShift (5)• PID Y2 Diff (6)

• When the controlling temperature sensor is set toselect the Load LW Temp, the setpoint control will operate strictly in a proportional mode with offsetsand differentials used to determine the appropriate capacity to use. In this mode, the following parametersare used:

• Stage Delay (30)• Gain (2)• PIDY1 Ref (7.2)• PID Y1 Diff (7)• PID Y2RefShift (5)• PID Y2 Diff (6)

• The default values were used in the test lab and seem to be a reasonably good beginning point forparameter settings.

Envision2 NXW Application Datapp1.0. Minimum Fluid Volume

A. Water-to-water heat pumps require a minimum amountof source and load side fl uid volume to ensure accurate and stable temperatures during system operation. For normal air conditioning type applications, it isrecommended to use at least 7 gallons/ton.

B. Applications that require more precise temperaturecontrol or low loading will occur the minimum fl uid volume shall be no less than 10 gallons/ton. Installation of a buffer tank that will properly mix thefl uid is recommended.

1.1. Water-to-Water Heat Pump Sizing

A. Heat pumps should be adequately sized for optimal system effi ciency and run time. Oversizing by more than 15% can diminish performance resulting in higher power consumption, short cycling of compressors, and unstable conditioning temperatures.

B. In applications where the minimum load is signifi cantlyless than the design condition, it is better to install 2 smaller heat pumps for load matching rather than a single large heat pump.

1.2. Heat Pump Piping

A. Multiple heat pumps can be installed in series or parallel confi gurations. The preferred system design is to pipe the equipment in parallel due to its simplicityand fl exibility. In parallel systems, the heat pump equipment can vary in size as long as fl ow rate and system volume are accounted for.

B. Piping equipment in series is not desired; however, it can be done if proper guidelines are followed.Always observe proper temperature and fl ow rate requirements for each unit. Sometimes this method is desired to achieve larger temperature differences.

1.3. Strainers

A. All brazed-plate heat exchangers shall have astrainer within 8 ft of the water/brine inlet. It is highlyrecommended to use a minimum of 60 mesh in order to provide maximum fi ltration. In any case, the strainers should never have a mesh size less than 20.

B. Failure to install proper stainers and perform regularservice can result in serious damage to the unit, and cause degraded performance, reduced operating life and failed compressors. Improper installation of theunit (which includes not having proper strainers toprotect the heat exchangers) can also result in voiding the warranty.

C. Strainers should be selected on the basis of acceptable pressure drop, and not on pipe diameter. The strainers selected should have a pressure drop at the nominalfl ow rate of the units; low enough to be within the pumping capacity of the pump being used.

1.4. Flow Sensing Devices

A. A fl ow switch or equivalent must be installed on theevaporator for each unit to be installed. If the unit is to operate as both modes (heating/cooling), a fl ow switchis needed on both heat exchangers.

B. A differential pressure switch can be used in place of afl ow switch. The differential switch must be capable ofpressure range as indicated in the pressure drop tables.

1.5. Water Quality

A. General: Reversible chiller systems may be successfully applied in a wide range of commercial and industrial applications. It is the responsibility of the system designer and installing contractor to ensure that acceptable water quality is present and that all applicable codes have been met in these installations.

B. Water Treatment: Do not use untreated or improperly treated water. Equipment damage may occur. The use of improperly treated or untreated water in thisequipment may result in scaling, erosion, corrosion, algae or slime. The services of a qualifi ed watertreatment specialist should be engaged to determine what treatment, if any, is required. The productwarranty specifi cally excludes liability for corrosion, erosion or deterioration of equipment.

The heat exchangers in the units are 316 stainless steel plates with copper brazing. The water piping in the heat exchanger is steel. There may be other materials in the building’s piping system that the designer may need to take into consideration when deciding the parameters of the water quality.

If an antifreeze or water treatment solution is to be used, the designer should confi rm it does not have adetrimental effect on the materials in the system.

C. Contaminated Water: In applications where the water quality cannot be held to prescribed limits, the use of a secondary or intermediate heat exchanger is recommended to separate the unit from thecontaminated water.

The following table outlines the water quality guidelines for unit heat exchangers. If these conditions are exceeded, a secondary heat exchanger is required.Failure to supply a secondary heat exchanger whereneeded will result in a warranty exclusion for primaryheat exchanger corrosion or failure.

WARNING: Must have intermediate heat exchanger when used in pool applications.

17


1.6. Insulation

A. Heat pumps are built with factory installed insulationon any surface that may be subject to temperatures below the room dew point.

1.7. Brine Applications

A. Applications where the leaving fl uid temperature goes below 40°F a suitable brine solution must be used.Failure to do so can cause immediate damage to thesystem. The brine must be approved for use with heat exchangers. Automotive antifreeze solutions are not suitable for use in brazed plate heat exchangers.

B. The freeze detection must be adjusted appropriatelyfor brine applications. The brine solution concentration should be at least 15°F below thelowest leaving fl uid temperature.

Envision2 NXW Selection ProcessTo achieve optimal performance, proper selection of eachheat pump is essential. The easiest and most accuratemethod to size and select heat pump equipment is to useWaterFurnace’s WeDoGeo selection program. Specifi cdesign information such as temperatures, voltages, and fl ow requirements are entered directly into the program so that the correct heat pump is chosen. The heat pump schedule and submittal data is all generated withinWeDoGeo.

Notes before selections:• For applications using water, the leaving water

temperature must stay above 40°F.• If leaving water temperature below 40°F is desired, the

design must include a suitable brine solution. • Water/Brine fl ow rates must meet the minimum and

maximum criteria as established in the engineering data.• Water quality must comply with data presented in

engineering documentation.• Contact factory for applications requiring load

temperatures below 32°F

flow rate shown is optimum for geothermal closed loop systems and the suggested flow rate for boiler/tower applications.

• Water temperatures below 40°F assumes 15% antifreeze solution.

• Interpolation between ELT, EST, and GPM data is permissible.

• Operation in the gray areas is not recommended.

• Any flow rate less than 2.5 GPM/per ton requires a flow switch
